Specification of Letters Patent.

Patented Man. 27, 191?.

To all whom it may concern:

B it known that I, JOSEPH E. SCHUBERT, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Type-lVriting Machlnes, of which the following is a specification.

This invention relates to typewriting machines of the special kind shown in a patcut to Wernery and Smith, 1,132,055, in which the paper is supplied in the form of a continuous Web or Webs arranged in several plies, and in which carbon sheets are placed between the plies of the webs to be carried around the typewriter platen therewith. These carbon sheets are mounted upon a supplemental truck or carriage,

which is movable toward and away from the typewriter platen, whereby the carbons may feed forwardly at the line-spacing operations and thereafter return to position to be used with a fresh portion of the webs.

One of the objects of the present improvements is to secure a better control of the webs as they feed into the typewriting machine, and especially to adapt the machine for use with rolls of different widths successfully.

To this end, I arrange upon said supplemental carriage or truck side gages for the portion of the webs overlying the truck; said side gages being adjustable toward and from each other, and traveling with the webs toward the platen, whereby the webs are fed truly to the platen without liability of skewing sidewise, and whereby, when said supplemental carriage or truck returns to normal position, said guides will correct thelateral position of the webs, if the same should have become misplaced in feeding into the machine from the supply roll or package.

Over these side gages, I also mount a device to prevent the supply web from being displaced upwardly, said device being in the nature of a transverse bar secured at its ends upon the ends of said supplemental truck or carriage, and preferably overlying the side gages between their front and rear ends. This confining bar is placed close to the table upon said supplemental carriage or truck, upon which the webs rest, and by means of said bar and the gages, it is found practicable to control webs of various widths, thereby increasing the usefulness of the machine, so that it will not be limited to use with webs of a single width.

The rear ends of the carbon sheets are shown in said patent as carried upon bars or fingers mounted in stepped relation upon saidtruck, the rearmost bar being the highest. The upper ply of the several plies of the web needs to be carried up over this highest bar, the next highest is carried over the next highest bar, and so on. This separation of the webs at this point is liable to produce difficulty, particularly Where the plies of web are separated from one another, instead of being folded edgewise, the difiiculty being due to the length of the web, which is not supported between the highest bar and the rear end of the paper support; but this difficulty is overcome in the present invention, by placing a cross bar or device upon all the webs in rear of the rear-most bar which carries the upper carbon and in the vicinity of said bar, and a little above the bed or table portion of the supplemental carriage or truck, whereby the webs are held in confinement until they have nearly reached the carbon-holding portions, whereby satisfactory control of the webs is secured.

Other features and-advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a perspective front view of an Underwood typewriting machine provided with the mechanism disclosed in said patent and also provided with the present improvements. 1

Fig. 2 is a perspective rear wiew of the supplemental carriage or truck and showing the present improvements.

Fig. 3 is a sectional side elevation illus trating the course of thewebs and carbons through the machine.

The platen 1 is revolubly mounted in the carriage 2 and is connected by a gear train 3 to a line-space wheel 4, the gearing permitting the platen to be lifted to straighten out the sheets and permit the carbons to draw back for use on the fresh portions of the web. The carbons 5 are held by bars or fingers 5, mounted on steps (yon-a secondary carriage or truck 7. which runs forwardly and backwardly on rails S, which extend rearwardly from the carriage. The rails 8 are connected by a bar 9, having a roll 10 to run upon the track 11, as said rails travel with the main carriage over the main carriage track 12; the carriage 7 having a table 13.on which the work may rest.

Upon said table, I arrange gages 14: for the opposite side edges of the webs, and make these gages adjustable, securing them by means of thumb screws 15, passing through slots 16 in flanges 17 turned downwardly from fiat portions 18, which lie upon the table 13.- The slots 16 permit the adjustment of either gage 14, thus gaging narrow sheets in a variety of positions, widthwise of the machine. These side gages, owing to the forward and rearward movement of the carbon-carrying carriage 7, exert the desired control over the webs 19, as already explained.

In rear of the carbon-holding. fingers or bars 5, I mount across the machine a horizontal bar 20, which may be secured by screws 21 to the ends of the secondary carriage or truck 7,-this bar 20 being arranged near the table 13, to prevent the webs jumping up from said table, being for this purpose placed close to the rearmost of the bars 5, and below the level thereof. The web, being confined at a point so close to the rearmost of the carbon bars 5, has no opportunity to become unmanageable and troublesome. This bar preferably overlies the side gages 14, so that the. web, whatever its width, is'confined on all sides at this portion of the machine. I

As the webs 19 are fed forwardly past the printing line during the printing operations, the interleaved carbon sheets and the carriage 7 are advanced therewith. The gages ll moving with the webs as they are fed to the platen, prevent them from becoming misplaced laterally, and the rod 20 prevents them from being misplaced in an upward direction. Before returning the carriage 7, after a section of the webs has been written upon, the platen may be displaced upwardly to free the carbon sheets and permit said carriage and carbon sheets to be returned, during which movement the gages 14, moving along the webs, correct any lateral displacement of the webs, so that they are accurately positioned for being again advanced with the webs.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim:
